Mighty Stainless Steel Lunchbox – 4 Compartments (1040ml) – Blue

The Mighty Stainless Steel 4-Compartment Lunchbox is a durable, plastic-free lunch solution designed to help reduce exposure to plastic and micro-plastics in everyday food storage. Perfect for school lunches, work meals, and family use, this eco-friendly lunchbox makes it easy to switch away from plastic containers without sacrificing convenience or organisation.

Made from premium food-grade 304 stainless steel, this lunchbox is a long-lasting alternative to plastic food containers that can degrade over time and potentially contribute to micro-plastic exposure.

Designed to Reduce Plastic & Micro-plastic Exposure

Unlike traditional plastic lunchboxes, the Mighty 4 is made from stainless steel with no plastic food-contact surfaces, helping reduce the use of materials that may break down into microplastics over time.

It is ideal for anyone looking to create a low-tox, plastic-free kitchen and lunch routine.

Smart 4-Compartment Design for Easy Meal Prep

With four fixed compartments, this lunchbox makes it simple to pack balanced, organised meals without disposable bags or containers:

• 500ml main compartment

• 220ml section

• 200ml section

• 120ml section

• Total capacity: 1040ml

Perfect for school lunches, bento-style meals, snacks, fruit, and whole-food meal prep.

Leak-Resistant Silicone Seal (FDA & LFGB Approved)

The lid features a food-grade silicone sealing board (FDA & LFGB approved) designed to help reduce movement between compartments and support a more secure seal.

• When used with the silicone insert, the lunchbox is more secure and better at preventing spills between compartments, making it 100% leak-proof.

• The lunchbox can be used without the silicone insert, however it will no longer be leak-resistant or suitable for separating wet foods or liquids.
